Re: Re: Flow switch recommendations - and integration to HA server

[Neil Fuller <neil.fuller@xxxxxxxxx>]

Sorry Tracey!

VFC = Volt Free Contact, in other words, a pair of contacts used as an
input to switch something rather than supplying a voltage in to a piece
of equipment.

It's commonly used in Process and Heat, Vent and Air Conditioning (HVAC)
control.

Cheers

Neil
